Calcrostic Puzzle

We call these problems calcrostic because they are showing calculations in a form similar to acrostic word
puzzles. The color in the puzzle is used to indicate the computations in the rows, columns and diagonals. In a calcrostic, like:

ab × cd = ebaf
+×÷÷−
egf × h = hdc
=====
ejc × k = bfj

each letter represents a digit (one of 0,1,2,3,4,5,6,7,8,9). Equal letters represent equal digits, different letters represent
different digits. The 9 resulting numbers ab, cd, ebaf, egf, h, hdc, ejc, k, bfj may have more than one digit
(for example, ab is a 2-digit number) and are arranged in a 3 × 3 square as above. These numbers satisfy 3
horizontal, 3 vertical and 2 diagonal relations (like the diagonal relation ab × h = bfj where ×
stands for multiplication and ÷ for division. The problem is to find the value of each letter.
